Digital Modes in Coshocton

This is a new page on our website devoted to the digital modes. Here we explain some of the current digital modes that memebers are using for ARES (emergency services), and for everyday contacts. Some of the many modes include: PSK-31, RTTY, Olivia 8-500, MT63, APRS, (and even CW {the very first digital mode}).

We will try to list links and info. to help out the digital ham.

SWR Radiogram Broadcast

There is a broadcast station in Florida that transmits an AM signal using the ham digital modes. They transmit news, photos, information for a half hour on Sundays starting at 3:30PM local time on 7780KHz at 1500Hz on the waterfall. The station is WRMI. This is an interesting use of the digital modes for short wave listeners. We might learn something there. There is also a repeat of the program at 6:30PM local on the same frequency. The mode they use is MFSK32 among others. On Mondays they have an early morning broadcast at 3:00-3:30AM on 5850KHz and 7730KHz. All of these broadcasts are on the AM mode. Give a listen.

How to Configure FLDIGI

Warren WX8OH has found a very good set of tutorials on setting up and using fldigi and flmsg. It is by Rick Frost K4REF. He does a very complete job of guiding you through the set up and operation of this digital platform. They are found on youtube, and the one on configuration is found Here. You can also search youtube for Rick's videos by his callsign, K4REF.

These videos are helpful even if you have been using fldigi for awhile.
